R3 Vascular's ELITE-BTK pivotal trial of the Magnitude drug-eluting bioresorbable scaffold for below-the-knee PAD receives FDA IDE approval. The trial, set to begin in Q1 2025, aims to build on positive RESOLV1 study data and will involve up to 60 global sites and 264 subjects. Magnitude, made from a unique polymer, is designed to gradually absorb into tissue, leaving a naturally functioning vessel.
